Toxicity Assessment and Bioremediation of Deep Eutectic Solvents by Haloferax mediterranei: A Step Toward Sustainable Circular Chemistry

ChemSusChem, Accepted Article.
Understanding the toxicity of deep eutectic solvents (DESs) remains a major obstacle to large‐scale applications. Existing toxicity studies show inconsistent results due to the choice of different test organisms and methods, synergistic effects between DES components, and their interactions with culture media.
